CHURN-MOTOR.

SPECIFICATION forming part of Letters Patent No. 585,837, dated July 6,1897..

Application filed December 14, 1896. Serial No. 615,721. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM PLEASANT BLIss, a citizen of the UnitedStates, residing atAurora Springs, in the county of Miller and State ofMissouri, have invented certain new and useful Improvements inMechanical Motors for Ohurns; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to-make and use thesame.

My invention has relation to improvements in the construction of churns,and more particularly to amechanical motor for operating the verticalreciprocating dasher of an ordinary churn.

The object is to provide a simple, durable, and effective device forthis purpose; and to this end the novelty consists in the construction,combination, and arrangement of the several parts of the same, as willbe hereinafter more fully described, and particularly pointed out in theclaims.

In the accompanying drawings the same reference-numerals indicate thesame parts of the invention.

Figure 1 is a side elevation, partly in section, of my improvedchurn-motor. Fig. 2 is a rear elevation of the same. Fig. 3 is ahorizontal section of the line of the drivingshaft. Fig. 4 is a frontview of the crank. Fig. 5 is a cross-section of the crank-pin. Fig. 6 isa top plan view, and Fig. 7 is a detail of the dasher.

1 represents a suitable standard formed with integral horizontalparallel arms 2 and 3, which are provided with rectangular guideorifices4 4, which receive a vertically-reciprocating rectangular dasher-rod 5,the lower end of which is provided with a cylindrical stud 6, whichengages a circular orifice 7 in the dasher 8. A screw 9 serves to holdsaid dasher in place on the stud, and at the same time permits it torotate freelythereon while the rod is being operated.

The dasher itself is formed of two crossblades 10 10, which are arrangedwith their plane faces at a slight incline, so as to cause the dasher torotate on its own axis on the stud 6, and the blades are each formedwith a longitudinal fin 11, arranged at a right angle to the plane faceof the blade, which serves to retard the rotary movement of the dasher,and thus agitate the cream horizontally, while the vertical movementdisintegrates it to set free the butter globules.

12 represents ahorizontal cross-head which encompasses the dasher-rod 5,and is vertically adjustable thereon by the set-screw 13.

The face of this cross-head is formed with an integral crescent-shapedflange 14, and 15 represents a block provided with a vertical slot 16,through which a set-screw 1? passes to adjustably secure said block tothe face of the cross-head immediately below the flange 14. The upperedge 18 of this adjustable block is also crescent-shaped to conform tothe curve of the flange 14, the space between forming a groove 19, inwhich the crankpin 20 operates. This crank-pin is provided with afriction-sleeve 21, and the pin itself is formed integral with adovetail block 22, mounted in a dovetail groove 23 in the crank 24.

25 is a longitudinal screw mounted in the groove 23, its outer endengaging the block 22 and its inner end provided with a thumbgrip 26, bymeans of which the screw may be manipulated to increase or diminish thethrow of the crank-pin, and consequently govern the stroke of thedasher-shaft.

The crank 24 is mounted on the inner end of the short horizontal shaft27, journaled in the standard 1, and it is provided with a collar 28 anda hub 29, on which the operating crank-handle 30 is mounted.

3i represents the hand-grip of the crankhandle, and it is formed with alongitudinal pocket 32, closed by a removable screw-cap 33. A series ofremovable weights 34 34 are contained in the pocket, so arranged as tocounterbalance the weight of the cross-head, flasher-rod, and dasher,thereby enabling the operator to manipulate the churn at a minimumexpenditure of power.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, is

1. A motor for churns, comprising the vertical standard provided withthe horizontal arms, the rectangular dasher-rod mounted therein andprovided. with the rotatable dasher 8, the cross head 12 adj ustablymounted on said dasher-rod, and formed with an integral crescent-shapedflange 14, an adjustable block 15 secured to the face of saidcross-head, in combination with the shaft 27 provided with the integralcrank 24 having the dovetail groove 23, the dovetail block 22 mounted insaid groove and provided with the integral crank-pin 20 and sleeve 21,the screw 25, mounted in said groove in the crank and engaging the block22 and the crank handle 30, substantially as shown and described.

2. A churn-motor comprising the standard 1 provided with integral arms,the rectangular dasher-rod mounted in said arms and having its lower endformed with a stud 6, the dasher S mounted so as to revolve on saidstud, and formed with the inclined crossblades 10 having fins 11 11, thecross-head 12 adjustably secured to said dasher-rod and provided withthe integral flange 14 and the adjustable block 15 having acrescent-shaped edge 18, in combination with the shaft 27, the crank 24,the pin engaging the groove 19 in the cross-head, and the operatingcrankhandle 30, substantially as and for the purpose set forth.

3. A churn-motor comprising the standard, the rectangular dasher-rodmounted in said standard, the cross-head adjustably secured to saiddasher-rod and provided with the groove 19, in combination with theshaft 27,

.the pin 20. of which engages the groove 19 in said cross-head, and thecrank-handle secured to said shaft and provided with the hand-grip 81formed with the longitudinal pocket32 and removable screw-cap 33, andthe removable weights 34, substantially as and for the purpose setforth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
